[matthiewon]

Hi everyone,

Now I hold my digital asset in Ledger nanoS.

But I believe someday someone will success to hack the hard wallet too. Because If you use high spec PC, you can atack 24 phrases key soon. There are lot of genius (evil way)  people out there.

So My coclusion is the wallet using "multi signing secutrity" will be the safest wallet, either hard or soft, hot or cold.
Then I am looking for a wallet service usind multi sig, but I could found only one so far, BitGo.

For comparison, I need to check as many services as possible.

Here is my question:

Do you know or Do you use any Multi Sig wallet service for Ethurium and XRP.

I need your help.

Thanks
